During the short drive to Lydia's apartment you're excited to finally have sex with her. You're not sure why she suddenly has cat ears, but not complaining. You park next to her and she rushes to kiss you against the side of the car, pressing her body against yours. Then she takes you by the hand and leads you up the stairs to her second floor apartment. You notice she is barefoot and walking on the balls of her feet. There also seems to be something under the back of her dress.
Inside Lydia's apartment you catch sight of a variety of statues and posters depicting cats. As soon as the door is shut, she is all over you, making out with you. Hands are roaming all over and one of yours slides under Lydia's dress to investigate what you saw going up the stairs.
"You've got a tail!" you exclaim.
"I know! It feels amazing!" she replies. "But why am I turning into a catgirl ?"
"I don't know" you reply. Because of the genie, you really don't remember that this the result of your wish, although you have a vague feeling that this is somehow because of you. "But now I want to have sex with you even more."
"You better!" says Lydia. "I don't wait to wait any longer!"
You reach up with your other hand to find the zipper on the back of Lydia's cheetah print dress. You pull it down, and the dress practically falls off her. She leads you to her bedroom, removing her bra and panties. Then she bends over the edge of her bed, her tail high in the air.
As you move to finally consummate your relationship, you wonder just what kind of catgirl Lydia will become.
